Abstract
An electronic device includes a processor, a volatile memory, and a non-volatile memory. The non-volatile memory stores a first operating system, and the electronic device works in a first working mode and a second working mode. When the electronic device is in the first working mode, a second operating system is run in the volatile memory. When the processor detects that the electronic device reaches a preset condition for entering the second working mode, the non-volatile memory is enabled, and non-system data in the volatile memory is moved to the non-volatile memory. The non-system data does not include the second operating system. After the movement of the non-system data is completed, the volatile memory is disabled, and the first operating system is run in the non-volatile memory, so that the electronic device enters the second working mode.
